Datasheet Summary
Three-Rail Output Controller with Single Intel Proprietary Interface for Desktop and Notebook CPU Applications
.onsemi.
The NCP81245 (3+3+1 phase) three- output buck solution is optimized for Intel’s IMVP8 CPUs.
The two multi- phase rail control systems are based on Dual- Edge pulse- width modulation (PWM) bined with DCR current sensing providing an ultra fast initial response to dynamic load events and reduced system cost.
The single- phase rail makes use of ON Semiconductor’s patented high performance RPM operation. RPM control maximizes transient response while allowing for smooth transitions between discontinuous- frequency- scaling operation and continuous- mode full-...
